20120064886 | METHOD OF LOGGING MEASUREMENT RESULT AT HANDOVER FAILURE IN WIRELESS COMMUNICATION SYSTEM - Disclosed is related to a wireless communication system and a mobile terminal providing a wireless communication service and to a method by which a base station and a mobile terminal transmit and receive data in an evolved universal mobile telecommunications system (E-UMTS) evolved from universal mobile telecommunications system (UMTS), a long term evolution (LTE) system, or a LTE-advanced (LTE-A) system and more particularly, to a method of logging a measurement result at a handover failure. | 03-15-2012 |
20120099441 | APPARATUS AND METHOD OF PREVENTING COMPONENT CARRIER FAILURE PROPAGATION - Disclosed is a mobile communications system employing a plentitude of component carriers and carrier aggregation between a user equipment (UE) and a base station. When failure of any downlink component carrier (DL CC) or uplink component carrier (UL CC) has been detected, the UE transmits UL control signal (e.g., UL HARQ ACK/NACK) to the base station, by re-selecting a CC for UL transmission (e.g., activation of a control channel of a UL CC relating to the DL CC). This may prevent DL CC failure from influencing on a UL CC. | 04-26-2012 |

20130308548 | METHOD FOR REPORTING MEASUREMENT INFORMATION OF TERMINAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS THEREFOR - The present invention relates to a method for enabling a terminal to process a signal in a wireless communication system. Specifically, the method includes the steps of: selecting a cell according to a measurement based on a first sub-frame pattern; transmitting a first message to the cell; and receiving a second message from the cell on the basis of a second sub-frame pattern, wherein the first message indicates that the measurement is performed on the basis of the first sub-frame pattern. | 11-21-2013 |
20140016593 | METHOD FOR TRANSMITTING AN UPLINK SIGNAL, METHOD FOR RECEIVING AN UPLINK SIGNAL, USER EQUIPMENT, AND BASE STATION - The invention relates to a method comprising classifying user equipment (UE) cells, to which carrier aggregation is applied, into a plurality of time advance groups. Uplink-time synchronization is managed using the time synchronization of a primary cell (Pcell) in the time synchronization group to which the primary cell belongs. For other time synchronization groups, the uplink time synchronization is managed using the time synchronization of a secondary cell (SCell) that is particularly set in the relevant time synchronization group. Thus, the plurality of time synchronizations can be effectively managed for the UE and a base station (BS). | 01-16-2014 |
